CAR-COUPLING.

Specification of Letters Patent.

Patented July 2, 1907.

j'o all 'lr/ioni. it may concern:

o it known that l', WILLIAM S. SonnoEnEn, a citizen ofthe United States, residing in Chicago, inthe county of tlnok and State 'of Illinois, have invented a new and useful Improvement in Car-Couplers, of which the following is n specification.

My invention relates to improvements in Car couplers of theltl :ist-er (Jar Builders typo, having the customary forked dntwhead and pivoted knudkle, and avertically movable gravity lock. L

The object of niy invention is to provide a co1' coupler of the Master Car Builders type which will be of a simple, stning, efficient and durable construction, in which the vertically movable lock will itself have provision for throwing the knuckle open and setting the lock in position. for coupling and nncoupling, and in which the vertically movable lock will be opera-ted from the eide instead of from the top or above. A top lift lock, or one which is .iperated from above, is, in many cases, objectionable, owing to the danger of the lifting lever or its connection with the lock being torn off or broken, either by the draft rig Ting giving way or in loading material on flat or other cars, or owing to the lifting chain or connection being too long and dropping down between the deadwood and the horn of the coupler.

My invention consists in the means I employ to prac-` tically accomplish the above mentioned object, as here-5 in shown and described and more particularly specified in the claims.

1n the accompanying drawing, forming a. part of this specification1 Figure l is a longitudinal vertical section of a car coupler embodying my invention, showing the lock in position for holding the knuckle closed. Fig-2 is a similar view showing the lock in its lock set position for uncoiipling. Fig. 3 is a horizontal section on line 3 3 of Fig. l. Fig. 4 is a vertical cross section on line 4 4 ofFig. l, showing the lifting lever and its extension in elevation. Figs. 5 and (i are views similar to Figs, l, 2 and 3, but illustrating the operation of the lifting lever and lock in throwing the knuckle open. Fig. 7 is a detuil plan view. Fig. 8 is a detail Side clevation of the lock. Fig. 9 is a detail front elevation of the lock. Fig. l() is a detail perspective view of the lifting lever.

ln the dra-wing A represents the draw-head -of the coupler, having the customary pivot nrni a. and guard arm ri'.- .l the knuckle, having Linl custom-.Inv front urni or nose b and roar al'ln or tail b, (-thc pivot pin; l) the vertically movable side-lift lock fitting in the vertical aperture a2 of the drow head; and F the side or laterally extending lifting lover, and l"l the crank :uin oxtension thereof. lThe draw-head A has a lock set seat a" in its lower web or floor a" adjacent to .the lock aperture o therein. The rear arm or tail b' of the knuckle is furnished with the customary hook or extension b2, and with a flat upright face b to engage the lock. The rear arm or tail of the knuckle is also provided on its under side with an upwardly and laterally extending knuckle throwing incline b4, and preferably also with an upwardly and laterally extending incline bf on its upper side, so that as the knuckle swings open this latter incline will lift the lock off the lock set seat of the draw head.

'lhe lock D is provided at its lower ond with a downwardly and forwardly projecting lock set leg or extension d, having '.t curved or cannlike upper face .71 adapted to engage the knuckle throwing incline b4 on the rear arm or tail of the knuckle to throw the knuckle open. The vertically movable gravity lock D is provided on the knuckle side thereof with a recess rl`-, having on upper curved or cam-like wall or face il for the bent lifting armfef the lifting lever F to engage or slide and lift aga-inst, and having a lower wall or stop shoulder (Z4 which serves as :i stop for the lifting arm of the lifting lever F to engage when the lock is raised to its full extent, thus limiting the turning movement of the lifting lever. This shoulder rld1 also nets as a stop to prevent creeping of the lock when the knuckle and lock :tre in their closed or coupled position by engagement with the lower end of the lifting arm f, as will be readily understood from Fig. l ofthe drawing. The recess d2 also has an up'right back wall d5.

The side or laterally extending lifting lever F extends horizontally through o. side opening or bearing a in the draw head above the knuckle tail, and the draw head is preferably provided with upright lugs a aG between which the side lifting lever F fits. A removable pin G extends through one of these lugs a to hold the laterally extending lifting lever F in place. The side opening a of the draw head .for th o lifting lover is preferably slightly elongated vertically, und the lifting lever is furnished with e rounded or eurvod heel fl to adapt it to he readily inserted and removed from the draw head when the pin G is removed. 'lhe horizontal zi-rin of the side lifting lever l1 is provided with a. cam or eccentric f f, to increase thrthrow of ils lifting :n'in

on the lock when the lever is turned and to complete the lifting of the lock to the required extent to throw the knuckle completely open.

Tho outer end of 4tho side lifting lever lf is provided Willian uyef'" to engage the hook cyef" of the lifting lever extension F', having the operating :lrin oiterank f5, :ind which extends to the outside of the car. The

crank :il'in extension 1*" of the .lift ing lvvcr is loosely su p ported by a hnwkct l Secured to the front of the car. The loose or l riucl`rle-joint-like connection f f4 between the lifting lever F and its extension F, en ahles the draw head of the coupler to move hack and forth or up and down as required, without causing any binding or stricture between the lifting,r lever and its extension.

The vertically inoval'ile,sidelift,gravity lock D is provided at its front corner with a shoulder d which is adapted to ride or rest upon the rear arm or tail of the knuckle when the knuckle is open or'svvinging open, and thus set or support the lock in position for coupling when the knuckle again closes.

The draw head A is preferably provided with an inclined projection a7, under which the lock set and knuckle throwing ler,r orextension rl o the lock fits when the lock is in its'lowerrnost or closed position, which also aids in preventing the lock from creeping when the cars are coupled together, When the lock is lifted by the lside lifting lever F the 'lower end of the lockswings slightly backward at the initial upward moveinentto permit the knuckle throwing leg 'to clear this rearward projection a7 of the draw head.

The operation is as follows: When the lock is lifted yloy turning of the lifting lever F, the lifting arm f thereof engages the curved or cam-shaped lifting shoulder or upper wall d3 of the recess a"-l near the front side there! of, and lits the lock upward, the lower end of the lock at first moving slightly backward to clear 'the lock creeping prevention shoulder al of the draw head, and the further turning movement of the lifting lever 4throwing the lower' end of the lock forward, so that the lock set toe or edge of the lock set leg d will overhang,r the lock set seat a3 of the draw head, and thus positively insure the proper engagement of the lock with` kthe lock set seat of the draw head when the lock is permitted to again drop or descend by. the operator releasing or letting go of the lifting lever F. When it is deA sired to throw the knuckle open lfiyoperation of the ver` by its engagen'ientwith the curved lifting shoulder or cam d? on the lock, raises the lock until the knuckle `throwing cam orincline dl on :the lock engages they knuckle throwing carri` or incline bi on the rear arm or tail of the knuckle, and as the .lock is further lifted i thnows the knuckle open; the operation of the lifting arm of the lifting lever on the curved lifting shoulder d of the lock, also causesithe'lower end of the lock to move y forwaild andfollow'the knuckle tail in its opening movement as the lock is further raised.l lWhen the lock 'is at the lock set position, as Shown in Fig. 2, when Y the knuckle swings open thehincline tg on the rear arm or tail of the knuckle lifts the lock o fi` the lock set and forces the lower end of thelock slightly backward so that the lock will properly clear the lock set seat as Vof,

the draw head and drop certainly to position when the knuckle again closes in `coupling. When- 4the' lock drops to the closed or coupled position it carries with it the inner arm f ofthe lifting lever, so that this farm their hangsstraight downwards, as shown in Figi, and

is thus Vin position by engagement of its lower end' with lclaiin Il, in a rar coupler, the combination with u forked draw-head having :i lock aperture in its wall to upper receive und huido the lock :iurl u lo( of a knuckle having u knuckle throwing 'ts' reni' arm, und u vertically sliding gravity lock exl'eniliiig through the upper wall ol' the draw houd und having :it its lower end a downwardly und forwardly extending l set and knuckle throwing' leg', and urovidml :il side with i gage the li vim,r arm o1' n li'l ug lever, und u side lifiini., Alever extending holfi' ntnllgv llirough the side wall ol: tue draw head und having :i lifting rui lilling in sai rec of the lock and engaging the lifting` shoulder ther-eel', suhstuntizilly as specificati,
